提出了一种将压力连续监测与水力瞬变计算相结合的管网突发检测与定位算法。该方法是为管网中管壁或其他物理元件突然破裂并伴随着在整个管网中传播的瞬变压力波而产生的中型和大型突发而设计的。在两个或多个点上测量的由脉冲引起的瞬变波到达时间和幅度被用来确定脉冲的位置。利用改进的累积和(CUSUM)变化检测测试来检测波到达时间和幅度。在实际管网上的验证结果表明，所提出的突发检测和定位技术在给水系统中具有潜在的应用前景。
An algorithm for the detection and location of sudden bursts in water distribution networks combining both continuous monitoring of pressure and hydraulic transient computation is presented. The approach is designed for medium and large bursts that are the result of the sudden rupture of the pipe wall or other physical element in the network and are accompanied by the transient pressure wave that propagates throughout the network. The burst-induced transient wave arrival times and magnitudes measured at two or more points are used to find the location of a burst. The wave arrival times and magnitudes are detected using the modified cumulative sum (CUSUM) change detection test. Results of validation on a real network show the potential of the proposed burst detection and location technique to be used in water distribution systems.
